as I understand it , cyberknife type radiation is so concentrated, that scatter is much less to the thymus and bones with marrow with blood-forming potential

It is the external beam radiation given for breast cancer which was studied in the papers I quoted.

Noone has been studying this in breast cancer patients much of late.

I suggested to someone doing a trial of accelerated partial breast irradiation, that they study the immune system of those who do not get radiation therapy, those who get APBI and those who get conventional radiation therapy, but I think the problem is getting the funds.(no drug company support,)few studies look at whether less of a tretment is equivalent to more because of legal reasons and probably difficulty finding willing patients.
